  • “Don’t you wonder sometimes ‘Bout sound and vision?” —David Bowie To create a coherent representation of the world, the brain must consolidate information across different sensory modalities

  • It was believed that information from multiple senses was integrated in higher cortical areas, after being processed independently in primary sensory areas

  • What is the computational advantage of multisensory enhancement in primary sensory cortex? Recent imaging studies in mouse visual cortex have shown that concurrent auditory stimuli can enhance visual coding by sharpening tuning and mod

Introduction

“Don’t you wonder sometimes ‘Bout sound and vision?” —David Bowie To create a coherent representation of the world, the brain must consolidate information across different sensory modalities. Recent imaging studies in mouse visual cortex have shown that concurrent auditory stimuli can enhance visual coding by sharpening tuning and mod- Activating auditory and somatosensory cortices elicit similar responses in visual cortex, indicating that the mechanism behind crossmodal integration may be broadly similar across non-primary modalities (Iurilli et al, 2012).
